摘    要:远洋渔业是碳汇渔业的组成部分之一,不仅为消费者提供高品质水产品,同时还具有碳汇功能。在初步构建金枪鱼渔业碳汇评估模型的基础上,借助印度洋金枪鱼委员会(IOTC)提供的中国产量数据,结合捕捞种类的营养级,分析了1995-2012年中国的印度洋金枪鱼渔业碳汇量变化情况。结果表明:在1995-2012年间,金枪鱼渔业平均营养级处于4.34~4.45之间,其中4.41~4.45出现的频率为66.66%;整体评估模型的碳汇量测算平均值为54.13万t,在2006年达到峰值,约124.51万t;分种类评估模型碳汇量的主要贡献种类为BET、YFT和ALB,碳汇量平均值为55.05万t,2006年峰值为125.83万t;两种评估模型测算结果的变化趋势一致,但整体评估模型的测算值偏低,相对差额平均值为2.35%;为了准确评估金枪鱼渔业碳汇量,需要加强对分海域、分种类及分生命周期的金枪鱼食物网能量传递效率进行系统研究。

关 键 词:印度洋  金枪鱼渔业  碳汇渔业  碳汇量评估  营养级

Abstract:Pelagic fishing is an integral part of the carbon sink fishery, which not only provides consumers with high quality aquatic products, but also has a carbon sink function. Based on the assessment model Ⅰ and Ⅱ, the tuna fishery carbon sinks of China was evaluated by the data provided by Indian Ocean Tuna Commission (IOTC) and integrated with related information on trophic level from 1995 to 2012. The results showed that the mean trophic level of tuna fishery was between 4.34~4.45 from 1995 to 2012, and the frequency of 4.41~4.45 was 66.66%. The average carbon sinks of assessment model Ⅰ was 541 300 t, and the peak was 1 245 100 t in 2006. The species of BET, YFT and ALB were the major contribution to carbon sinks assessment model Ⅱ, the average value was 550 500 t, and the peak was 1 258 300 t in 2006. The results of assessment model Ⅰ and Ⅱ had the same trends, but the measuring value of model Ⅱ was lower, and the relative difference between them was only 2.35%. The systematic studies on energy transfer efficiency of tuna food web in different sea, species and life cycle should be carried out in order to accurately assess the amount of carbon sinks of tuna fishery.
Keywords:Indian Ocean  tuna fishery  carbon sink fishery  carbon sinks assessment  trophic level
